Shock absorbing casters offer many benefits, including
Protecting cargo from damage
Reducing noise due to vibration
Easier to roll than conventional casters when the flooring is cracked, uneven or encountering obstructions like thresholds
Reduces risk of damage to flooring
However, not all shock absorbing casters actually create a benefit.Shock absorbing casters are usually spring loaded, and those springs deflect when pressure is applied to them. If the caster uses the wrong springs, it could potentially do more harm than good. If the springs are too firm, they could actually cause more vibration and potentially noise and damage to contents. If the springs are not firm enough, it would be like there is no shock absorption at all. Therefore, it is very important to provide an accurate weight for the load. Exceeding the rated capacity on most spring loaded casters could render them useless, and to light of a load, could create excessive vibration.
